AppGW is a a regional load balancer and cannot be used to failover to a secondary region if the primary region fails. So cannot use AppGW

You would have to use Azure Front Door for regional layer7 load balancing

This is yes : Application Gateway backend pool members aren't tied to an availability set. An application gateway can communicate with instances outside of the virtual network that it's in. As a result, the members of the backend pools can be across clusters, across datacenters, or outside Azure, as long as there's IP connectivity.

application gateway only supports high availability within the region. hence No is the correct answer. How does Application Gateway support high availability and scalability? The Application Gateway v1 SKU supports high-availability scenarios when you've deployed two or more instances. Azure distributes these instances across update and fault domains to ensure that instances don't all fail at the same time. The v1 SKU supports scalability by adding multiple instances of the same gateway to share the load. The v2 SKU automatically ensures that new instances are spread across fault domains and update domains. If you choose zone redundancy, the newest instances are also spread across availability zones to offer zonal failure resiliency.

@Kewl. I think the answer should be yes. here is copy and paste from the link you shared that app gateway v2 support zone redundancy ..Zone redundancy: An Application Gateway or WAF deployment can span multiple Availability Zones, removing the need to provision separate Application Gateway instances in each zone with a Traffic Manager. You can choose a single zone or multiple zones where Application Gateway instances are deployed, which makes it more resilient to zone failure. The backend pool for applications can be similarly distributed across availability zones.
